Cook potato in a saucepan of boiling, salted water until tender. Drain. Remove to a bowl and roughly mash. Allow to cool for 15 minutes. Add tuna and onion. Stir to combine. Using damp hands, shape into 8 oval patties.

Step 2

Place flour on a plate. Place egg and breadcrumbs in separate bowls. Dust patties lightly in flour, shaking off excess. Dip in egg, then breadcrumbs. Heat oil in a large frying pan over medium heat. Cook patties for 3 to 4 minutes each side or until golden brown. Remove to paper towel to drain. Allow to cool.

Step 3

Spread 1 tablespoon of hommus over 1 half of each pita bread. Top with onequarter of the lettuce and tomato. Top each pita bread with 2 tuna patties. Fold up to enclose filling. Cut each roll in half. Secure with baking paper and string.
